sheets for use in telegraphic typewriters, with arow of apertures ateach side margin for engaging pin-wheels at each end of the typewriterplaten, so that the pile of strips would be fed in strict coordinationwith the rotation of the pin-wheels under the control of the telegraphictypewriter. These pin-wheel apertures were located in margins whichcould serve no other useful purpose, and the arrangement referred torequired that if a pile having a different width 'of strip was desiredto be used with the typewriter, the pin-wheels thereon would have to beadjusted toward or from each other to accommodate the new width of thestrip.

To avoid this, the present invention arranges the manifolding pile andthe typewriter so that manifolding piles having different widths ofworksheet strips may be used in the typewriter without necessitating anyadjustment or change of the typewriter (of course, within the capacityof the typewriter). For instance, according to the present invention, ina typewriter designed to take a strip 10 wide, strips from 10" down maybe used without necessitating any change being made in the typewriter.

This is accomplished by providing the typewriter with only one pin-wheellocated at the end of a platen and providing a pile of worksheet istrips with pin-wheel apertures at only one side edge.

Several embodiments of this invention are shown herein. In one of these,the pins and the pin-wheel apertures are located on the left side P ofthe typewriter and pile respectively, when it is desired to write closeto the right-hand edge of the strips, and in the other the pin-wheelsand pin-wheel apertures are located on the righthand side of thetypewriter and pile respectively,

when it is desired to write close to the left-hand edge of the pile. v

As indicated in the accompanying drawings,

the manifolding pack of the present invention comprises a plurality ofcontinuous worksheet strips l0 each containing a succession of printedforms II. The worksheet strips l0 are interleaved \m'th continuouscarbon strips l2 so that when the pile of strips is supported upon aplaten 80 I3, or other writing surface, writing operations, as, forinstance, impressions of types M, will be transferred to the underlyingworksheet strips Ill by the carbon strips 12. The pile of strips ispreferably provided with transverse perforations 85 I5 between printedforms It so that when one set of forms I I has been written upon, it maybe severed from the remaining portions of the strips by tearing alongthe line of perforations l5.

In order to keep the worksheet strips in regis- 44) tration with eachother and in strict coordination with the feed mechanism of thetypewriter, it was customary heretofore to provide the pile of strips ineach side margin with feeding bands, each containg a row of apertures tobe engaged by pin- 45 wheels on the typewriter platen or associated withthe writing surface and controlled by the feed mechanism. Thisnecessitated the provision of a margin on each side of the pile whichcould serve no other useful function than to constitute feeding bands,and thus represented an added expense so far as the function of makingwritten records is concerned. It also necessitated provision ofpin-wheel feeding devices at each end of the platen and at predeterminedplaces a thereon and would only permit the use of different widths ofpaper in the same machine by changing the location of the pin-wheels,usually by the substitution of a new platen with the pin-wheels locatedat desired distances apart.

It has been found by the present invention, however, that theregistration of the strips and their coordination and aligning with thetypewriter feeding devices may be satisfactorily effected with only onerow of pin-wheel engaging apertures and one pin-wheel, preferably at oneside or the other of the pile and platen, respectively.

Accordingly, in the manifolding piles illustrated herein, the worksheetstrips I are provided at one side edge only with a longitudinallyextending margin "5 having a-row of apertures l1 adapted to engage pinsI 8 on pin-wheels l9 attached to the typewriter platen l3. As usual,there are a sufflcient number of pins 18 around the platen so that atall times a plurality of pins engages the apertures l1 and thereby holdthe pile of strips in alignment with the typewriter platen and cause itto move coordinately with the platen in its feed-movements. By having asingle pinwheel I!) located at or near one end of the platen, the pileof strips maybe 01 any desired width within the range for which theplaten is constructed without necessitating any adjustment orrearrangement of the platen or the pin-wheel.

According to the present invention, I secure the worksheet stripstogether throughout the length of the feeding bands 16 when making thepile, as, for instance, by gum 20 (see Fig. 2), while at the same time Iaccurately register the worksheet strips with each other. By so doing,there is formed a laminated feeding band 2|, made up of the severalmargins I 6 of the worksheet strips, which is comparatively stiff andstrong and not readily tearable by the pins I8 during the feeding of thepile.

When the strips l0 are so secured together,

after the forms have been written upon and a set has been severed fromthe remaining portion of the pile, the laminated feeding band 2| may beremoved from the body portion of the worksheets or forms H by being tornalong a line of perforations 22 extending longitudinally of theworksheet strips and defining the inner boundary of the feeding marginsl6. This operation is indicated in Fig. 3, and by it the worksheets arenot only separated from the feeding band, but also from each other. Asstated above, the feeding bands l6 and pinwheels l9 may be located ateither the righthand or left-hand end of the pile and typewriter platen,respectively, the former arrangement is shown in Figs. 1 to 4 inclusive,while the latter is shown in Figs. 5 to 8, inclusive.

The carbon strips l2 may be unattached to, and structurally separatefrom, the worksheet strips or the bands It thereon, as shown in Fig. 2,in which case the lateral edge 23 of each carbon strip is nested in thepocket formed between the surfaces of the adjacent worksheet strips atthe junction thereof with the feeding bands which are held together bythe adhesive or gum 20, and thus the carbon strips are held in the pileagainst lateral movement in one direction. When this arrangement isused, it is preferable that the laminated feeding band 2| be provided onthe right-hand side of the pile as shown in Figs. 1 to 4, because whenthus arranged, any tendency for the carbon strips to shift laterally ofthe pile as a result 'of the abrupt stopping of causes the lateral edge23 of the carbon strip to 1 more snugly fit into the pocket abovereferred to between the surfaces of the adjacent worksheet strips.

In this case, when the laminated feeding band 2! is torn off, the sheetsresulting from the carbon strips l2 and the forms H are structurallyseparate and may be removed from each other in the usual manner.

In some cases, however, it is preferable to have the carbon stripssecured to the worksheet strips to be drawn along thereby and to preventthe carbon strips from shifting laterally independently of the worksheetstrips. This is accomplished in the form shown in Figs. 5 to 8, in whichthe lateral edge 23a of each carbon strip is caused to extend intosuper-position with the feeding bands lBa preferably so that the edge23a is tangential with the pin-wheel apertures I la, and in this way thecarbon strip is caught between the gummed-together feeding bands Ilia ofthe worksheet strips and secured thereto by the gumming operation. Inthis manner there is formed a laminated feeding band 2la which containsnot only the worksheet strips but also margins of the carbon strips.

If desired, the carbon strips could extend for the full width of thefeeding bands IBa, in which case it would be necessary to provide in thecarbon strips pin-wheel apertures like the apertures I I-Jla in theworksheet strips. However, this is avoided by having the edge 23a fallshort of the line of apertures Ila. By having the edge 23a of eachcarbon strip tangential with the pinwheel apertures, accuratepositioning of the carbon strips in the pile can be obtained during theoperation of collating and pasting the worksheet strips, for the edgesof the pins used in collating the strips may then constitute guides forcontrolling the position of the lateral edge 23a of the carbon strip.

In the embodiment of this invention shown in Figs. 5 to 8, the worksheetstrips are provided with lingitudinally extending lines of perforations22a at the junction of the feeding bands lfia with the main body of thestrips so that one or more of the written worksheets may be torn fromthe book-like set of written forms and so that the laminated feedingband 2 la may be removed from the worksheet strips, as described inconnection with the form shown in Figs. 1 to 4.

In the embodiment of this invention shown in Figs. 6 and 7, the carbonstrips also have longitudinally extending lines of perforations 24 sothat the carbon sheets may become separate and capable for use for otherpurposes by the operation of tearing the laminated feeding band 2| fromthe pile of sheets.

However, it is advantageous where conditions permit such an arrangement,to provide the pile as shown in Figs. 9 and 10, wherein only theworksheet strips are provided with the longitudinally extendingperforations 22a, and the carbon strips which are secured to thelaminated feeding band are not provided with such perforations. Whenthis is done, the worksheet strips at the edge opposite thelaminated'feeding band 2!a are preferably made to extend beyond theadjacent edge of the carbon strip. This may be done by making the carbonstrips narrower than the worksheet strips as shown in Fig. 9, or, byhaving the corner 25 of the carbon strip cut out as shown in Fig. 10.

When the pile is so made, the operator may 7 grasp the laminated feedingband with the fingers of one hand while the fingers of the other handmay grasp the portions of the worksheets which have no underlyingcarbon, and by moving the hands apart the worksheet strips are torn fromthe feeding band along the lines of perforations 22, and at the sametime the carbon sheets are separated from the worksheets by remainingattached to the laminated feeding band 2|a, as indicated in Fig. 10.
